Abstract

A transmission belt is formed by a plurality of elements each having: a body portion including a saddle surface that contacts an inner peripheral surface of an endless ring and a pair of pillar portions that are extended outward in the radial direction of the transmission belt from both lateral sides of the saddle surface; a first surface that is formed on one side of the body portion in the circumferential direction of the transmission belt and a second surface that is formed on the other side of the body portion in the circumferential direction of the transmission belt; and rocking edge portions that are formed at both lateral ends of the first surface so as to be separated from each other and that act as a fulcrum when adjacent ones of the elements contact each other and rotate relative to each other. The rocking edge portions are formed by a curved surface so as to have a width from a position outside the saddle surface to a position inside the saddle surface in the radial direction of the transmission belt. A portion connecting the first surface and the saddle surface is formed so as to be located closer to the second surface than the rocking edge portions are in the circumfer…
